Add a new variant for WeAct MiniSTM32H743VITX and MiniSTM32H750VBT (#1552)
The board schematics, images at the time of this commit is found athttps://github.com/WeActTC/MiniSTM32H7xxThis variant is 'unofficial' (i.e. this is community contributed and notfrom the original vendor)it is actually adapted from the generic variant found inhttps://github.com/stm32duino/Arduino_Core_STM32/tree/main/variants/STM32H7xx/H742V(G-I)(H-T)_H743V(G-I)(H-T)_H750VBT_H753VI(H-T)the changes are:1) created a void SystemClock_Config(void) that use the external 25 MhzHSE crystal. this makes it run at 480 Mhz ! USB (CDC Serial) stillworks per normal.much of the rest of the peripherals are clocked at 80 Mhz (from theoutputs of PLL2 and PLL3), that's the max allowable documented in refmanual for the ADC.2) the rest of definitions are pretty much same as the generic variantwith the following redefinitions a. #define LED_BUILTIN PE3 (per schematics and tested) b. #define USER_BTN PC13 (per schematics and tested) c. SERIAL_TX PA9, SERIAL_RX PA10 - this makes the 1st hardware serial port UART13) added 2 conveinence functions - this is only for this board and isonly availaible if it is selected /* power saving mode, mcu runs significantly cooler * Sysclock 240 Mhz, bus clocks 120 Mhz */ void SysClkHalfSpeed(); /* full speed - sysclk from PLL1 P - 480 Mhz * Sysclock 480 Mhz, bus clocks 240 Mhz */ void SysClkFullSpeed() This variant runs the systemclock default at 480 MHz (published max) and AHB at 240 MHz. The stm32h743 mcu tend to run pretty warm after a while (around 50 deg C). The half speed function call changes the system clock dividers (divide by 2 - gives 240 Mhz) and AHB dividers (divide further by 2 - gives 120 Mhz) so that it runs at 1/2 the PLL1 P speeds (480 Mhz). the mcu runs significantly cooler running at 1/2 speeds. some tests has been done to swtich the speeds calling the functions at run time, they seem to work ok. But tests isn't thorough, so check things if you use the speed changing functions.Signed-off-by: ag88 <ag88@github.com>Co-authored-by: Frederic Pillon <frederic.pillon@st.com>
